in the classrooms where I have been conducting research on student screencasting, one of the most remarkable and consistent unintended outcomes was that students, no matter how young or old, and no matter what discipline, intrinsically reflected, self-assessed, and adjusted their articulation of understanding. Even when the screencasts were being made for an audience of zero, this phenomenon occurred. None of the teachers involved in the study ever instructed students to play back their screencasts or make revisions. The students just did it.
